and continuously rotating the shaft 16 shown in Figs. 1 to 4 comprises a shaft 17 disposed at an angle to the shaft 16, a drivin'g connection between the shafts 16 and 17, means for elevating and depressing said shaft 17, and means for continuously rotating said shaft 17. The driving connection between the shafts l6 and 17 comprises a bevel gear 18 which is secured to the shaft 16 and. a bevel gear 19 in mesh with said gear 18 which is pivotally secured by a. pin

20 to the end 21 of the shaft 17 The gear 19 is held in mesh with the gear 18 by a block 22 which is pivotallymounted upon a shaft 16 between the bevel gear 18 and a collar 23 secured to the shaft 16, said block having a recess 24 therein for receiving a pin 25 whichis secured to the gear 19 and is revoluble within the aperture 24- of the block 22, and a groove .26 to receive the end of-a set screw 27 secured in theblook 22. Resultantly the pin 25 being rigidly secured to the gear 19 and revolubly mounted in the block 22, and the block 22 being pivotally secured to the shaft 16, the gears 18 and 19 will be'contin'uously in mesh with each other and form a driving connection between the shafts 16' and.17.

The means for elevating and depressing the shaft 17 so as to vertically reciprocate the shaft 16 comprises a cam 28 secured to the shaft 17 and movable within an aperture 29 in a supporting bracket 30, the shaft 17 being movable within a vertical slot, 31 in the bracket 30 adjacent the cam 28. Resulta gear 34 having a hub 35 revolubly mount ed within a bearing 36 in the bracket 30 and provided with an anuular groove 37 to receive the end of a set screw 38 secured E0 the bracket 30 to prevent endwise movement of the hub 35. A gear 34 is in mesh with a gear 39 integral with the, hub of the flywheel 40 which is mounted upon a shaft 41 secured to the cover of the'machine. The end 42 of the shaft 17 is operatively secured to the gear 34 by a link 43 which is pivotally secured to the end 42 of the shaft 17 by a pin 42 and whichis also secured to the hub by a pin 45, the pin 45 being disposed at an angle to the pin 44 to form a universal connection between the shaft 17 and the gear; 34.

The means for vertically reciprocating and continuously rotating the shaft 16 shown in Fig. 5 is similar to that shown in Fig. 2 with the. exception of the means for elevating and depressin'g'the shaft 17 and for continuously rotating the same. To accomplish the elevation anddepression of the shaft 17' to vertically reciprocate the shaft 16, the end 21 of the shaft 17 is provided with a slot 46 in which a pin 47 secured to thegear 19 is slidably mounted and the shaft 17 is journaled in the supporting bracket 30 and is bent at its end 42 and secured directly to the gear 34. Resultantly the rotation of the gear 34 will rotate the I shaft 17 andits end 21 being bent at an angle to the; end 42 and secured to the gear 19 will cause said gear to move up'and down and consequently raise and lower the shaft 16 to which said gear is operatively connected.

The means for vertically reciprocating and continuously rotating the shaft 16 I shown in Figs. 6 to 8 comprises a horizontal shaft 48 which is journaled in suitable bearings in a bracket 49 secured to the cover 14 of the machine, a driving connection between said horizontal and vertical shafts which provides. a means for continuously rotating and vertically reciprocating the shaft 16 and means for operating said horizontal shaft. 1

The driving connection between the shaft 48 and the shaft 16 comprises a crank 50 secured to the shaft 48 and having a spherical end 51 which-is slidably and revolubly mounted within a cylindrical slot 52 within one end 53 of a block 54, the other end 55 of said block being bifurcated and pivotally mounted on the shaft 16 and held against sliding movement by means of collars 56 secured to the shaft 16. A' ratchet wheel '57 is mounted on the shaft 16 between the bifurcations of the block 54 and a pawl 58 is pivotally secured to the end 65 of the block 54 by a pin 59, one end of said pawl engaging with the ratchet wheel 57 and the. other end 61 being curvedinwardly and engaged by a spring 62 secured to the block 54. Resultantly the crank 50 being offset from the shaft 48 and having its end 51 engaging in the end 53 of the block54 the .rotation'of the shaft 48 will raise and lower the block 54 and consequently vertically reciprocate the shaft 16 to which it is connected and at the same time the crank 50 will give a rotary movement to' the block 54, causing the pawl 58to turn the ratchet 57 to rotate the shaft 16.

.The means for continuously rotating the :chine by a belt connecting said fly-wheel with the Wheel 70 mounted on the-shaft 48.

It is also to be noted that while the bracket 69 is secured to the hinged cover 14 of the machine the axis of rotation of the flywheel 67 is coincident with the, pivotal connection of the cover and the machine whereby the cover is relieved of the weight of the fly-wheel should it be desired to raise the cover. a

The means for verticallyreciprocating and continuously rotating the shaft 16' shown in Fig. 9 is similar to that shown in Fig. 7 with the exception that instead of providing a crank for the shaft 48 the shaft 48 isbent at an angle from the point at which it is j ournaled in the bracket 49 and is provided at its bent endwith a sphericalportion 51 which similar to the spherical end 51 of the shaft 48 is slidable within the bracket 54 and the driving connection with this exception is similar to that previously described in connection with Figs. 6 to .8. The means continuously rotating the shaft 48 comprises levers \33 and 33,shown in Fig. 1, the lever 33 being eccentrically and pivotally mountedupon a gear is secured to the shaft 48' and which is in mesh with a gear 73 on the'hub'7 of the 'fiy-wheel 74 which is pivotally mounted upon the machine. Resultantly the bending of the machine 48 will cause its end-51 to move. upwardly and downwardly in a circular .path and consequently. elevate and 72 which depress the bracket 54 and the shaft 16 and I at the same time impart a rotary tendency to the bracket54 and by the means prev'iously'described in discussing Figs. 7 vand- 8 continuously rotatin the shaft 16.

' The-means for vertica 1y reciprocating and continuously rotating the shaft 16 shown in Figs. 10 and 11 comprises a horizontal shaft 75 similar to the shaft 48 and similarly mounted in a bracket 76 uponthe cover 14 of the machine, a driving connection between the shaft 75 and the shaft 16 to continuously rotate and vertically reciprocate said. shaft 16, and means for continuously rotating the shaft 75..

AQdriving connection between the shaft 16 andthe horizontal shaft 75 comprises an arm .77 which is secured to the end of the shaft 75 and .which is provided with an aperture 78 having oppositely beveled sides 79 which amazes are adapted to receive a square ended pin 80 which is journaled in a casing 81 pivotally secured to the shaft 16 by collars 82 which pinis provided with a worm gear 83 which meshes with a gear 84 secured to the shaft 16. Resultantly the rotation of the arm 77 will elevate and depressthe pin and at the same time cause it to rotate Within the casing 81 and consequently turn the shaft 16 through the worm wheel connection. The

means for continuously rotating the shaft 75 is identical with that for continuously rotating the shaft48 shown in Fig. 9.

The invention thus exemplifies a means for vertically reciprocating and continuously rotating the agitatorlshaft of the washing machine.
